The outer surface of the fuze 62 is a circular arc, the clamping plate 43 can be clamped to the fuze 62 through the setting of the positioning plane 63, so that the fuze 62 does not rotate when the elastic body 6 rotates, and the fuze 62 is tightened. During the rotation of the elastic body 6, the clamping plate 43 slowly moves downward, so that the clamping plate 43 can always clamp the fuze 62, avoiding the continuous downward movement of the fuze 62 during the rotation of the elastic body 6, so that the positioning plane 63 is separated from the clamping plate 43.

[0051] The upper portion of the frame 100 is provided with a second air cylinder 4, the second air cylinder 4 is connected with a moving plate 42 through the extension and retraction end, and the clamping plate 43 is installed on the moving plate 42.
